RT3WB080 Invalid field in CDB

[RMill19]

I have an RT3WB080 installed in a personal server. On startup, the controller always logs "Information" for each drive "Invalid field in CDB". It only appears once per boot and all the drives are tested with no bad blocks.

What does this mean and how to correct it? This started appearing after I replaced failure-prone Seagate drives with new WD Red 3TB drives.

Hello,

Our best recommendation is contacting our support group directly to extract the TTY logs from the controller and decode those to narrow the issue:http://www.intel.com/content/www/us/en/support/contact-support.html http://www.intel.com/content/www/us/en/support/contact-support.html

Thanks, I submitted a Service Request. I hope they don't come back say I need to pay for support or something. I'll update here when I get an answer so it can be found by others.

Hello,

The RAID controller you have is under support and please do not be concerned about any charges since the support we offer for our customers is completely free. We recommend sending logs to have a better idea of the whole RAID array configuration.

Thanks, I submitted both the event and TTY logs in the support request.

Intel support determined that this was an issue with the RAID card itself. After RMA and replacement, the issue is resolved.
